Engine oil Mobil or ZIC

Been using mobile 1 5w-40 Syn Euro. Fixed my vanos code.

I use 0w-40 euro blend Mobil 1 in the winter and royal purple 5w-30 in the summer and usually try to get an k&n filter or something of similar quality it’s not always about the name but its definitely worth some research

For my Z with 210k miles i switched to the one your holding and it burns less. I get an extra 150 to 200 extra miles compared to mobile 1.

I always use full synthetic Mobil 1 5W-30

There was a dude on YouTube that did a test. Mobil 1 performed the best, followed very closely by Amazon basics

Man, just changed out the oil in my 2000 Crown Victoria Police interceptor yesterday with this. I HAVE USED THIS VERY OIL for close to 20 years. My shit runs as good as it has since I first drove it out of the Orange count sheriff's dept, Parole dept. auction lot. Never use anything else.

When it comes to brands most good brands work fine like Mobil 1, Castrol, Valvoline and so on. All these oils even including the cheaper amazon brand oils have been tested by the American petroleum institute and they have a stamp on every bottle.

Since then, I've changed my oil to a low SAPS VW 504 Mobil 1 5w30 ESP X3 which according to lubrizol has superior resistance to deposit and sludge formation. At this point, I've got consumption down to around 1qt/1400 mi which is a great improvement from where it was before. Hoping for further improvements with time but pleased with progress.

I’m slowly switching to Mobil1 since I started doing oil analysis.

It has no sodium and therefore a good way to see if there is a coolant leak.

My 1.8T has just over 103k miles. I got it at 78k, and until about the 95k mile mark, I've been using M1 0W-40, then switched to M1 5w-40 Truck and Turbo-diesel, since I wanted peace of mind with its extra additives and protection. I figured since this oil is meant for high operating temps and high load in turbo-diesel engines, it would be just as good in my daily-driven and weekend-tracked 1.8T. I change my oil a few days before going to beat on it over the weekend, otherwise I'll change it every 3k to 5k miles. Also, I have had some valve noise (tapping of some sort), the whole time I've had the car. I'm guessing it's lifter noise. I'm not sure, but I was told to try a heavier weight to counteract it, hence the switch to the only decent 5W-40 sold on base. Still no difference in noise.
